Hopefully you guys can get things sorted on this front. In the mean time I have found a solution:

Install Keyword Search Addon - Select DuckDuckGo as keyword search, then under DuckDuckGo Features - select I'm feeling Ducky. This allows you to use DDG for "I'm feeling lucky" style searches within the location bar, and your choice of search provider in the search bar. It's a little slow with the redirect issue but better than not having it at all.
